Add Plugin settings for maximum products in list view

[swisschocolate]

Sometimes setting a maximum count of products in list view would be helpful, e.g. to teaser the five or so most recent products. In the plugin settings, after "Sort by" and "Sort direction" an integer input field for "maximum amount of found records" should be added.

@extcode What do you think. Should this be implemented?

I think we could/should provide such a field in version 5.1.
